Can't change the default zone of GCP Proxies

[LuongPhuHoa]

docker run -e USERNAME='xxx' -e PASSWORD='xxx' -e GCP_ENABLED=True -e GCP_PROJECT='xxx' -e GCP_SIZE='e2-micro' -e GCP_ZONE='asia-northeast3-a' -e GCP_SERVICE_ACCOUNT_KEY='xxx' -it -p 8000:8000 laffin/cloudproxy:latest

I tried this command but it always creates instances in the us default zone, I can't switch it to the different zone. Can you fix this ?

Thank you
